In Q20, ‘ANY DATA’ not only refers to quantitative data, but also qualitative and approximate/ imprecise data. All data on population size can be useful and interpretable, even if only available for some populations.
If the answer is Yes, a series of questions will appear asking about effective size, then census size data.
If the answer to Q20 is ‘No, but Census size data does exist for the species as a whole’ the user will be directed to Section 6: Modified Indicator 1 for the Entire Species within the Country of Assessment , skipping Section 5 entirely.
If the answer to Q20 is ‘No, the species has insufficient data’, the form will skip to Section 7: Indicator 3 .
Questions 21 and 22 are asking about the kind of population size data that might exist for the species. If ‘Yes’ is answered for either question, more detailed information related to effective population size and census size will be asked in Section 5: Indicator 1. If ‘No’ is answered for either question, follow-up population size questions in Section 5 will not be presented.
If ‘No, but other genetic diversity information does exist” is selected for Q21, then no effective population size questions will be presented in Section 5.
